Giuseppe I don't really have such a document at hand myself. I would think that a physics teacher or a good beginner's book in metrology would be a good source for basic definitions and learning examples.
For examples of each concept I would use something along these lines.
Accuracy: Brad measures the outside diameter of a washer to be 0.20 inches, the true value of the OD is 0.20 inches and therefore his measurement is accurate. (so accuracy is described as a comparison of a measured value to it's true value)[it should be noted that the true value of a measurement can be infinitely small and therefore can never truly be known]
Precision: Brad uses a different instrument to measure the OD of the same washer and it reads 0.22" so he measures 10 more times and gets the same reading all ten times....it would be said that the instrument is very precise but not accurate.
Uncertainty: Brad uses his superior metrology skills to assess the uncertainty of measurements in his caliper as +/- 0.0005". In this way Brad can safely say that measurements made by this instrument utilizing a sound measurement method in a controlled setting will be within that interval 98% of the time.
These are pretty simplified examples, and as I said I'm sure you could find better ones from a physics teacher or a physics book but I hope this is of some help to you.
